Facebook share - content being posted is wrong

I have a bit of a puzzle which I hope you can assist me with.

When I 'like' or 'share' to Facebook the content that appears in the pop up is old page content that has been edited and the new content doesn't appear. This is not repeated for every page on my site but there are numerous other examples where this is happening.

It doesn't appear to be cached content as I have cleared all the cache both through the Joomla control panel and manually using FTP to ensure nothing was held in cache.

Am I missing something - is there a cache somewhere that JFBConnect uses that is separate from the normal Joomla cache?

There are two images attached - the first is the current page and the second is what is being sent to Facebook and this was the previous content.

Any advice on this?

Many thanks for your prompt response Melissa and helpful comments.

I didn't realise that Facebook is 'scraping' the content and this will explain why the old content is still showing - it is actually a Facebook cache that is in effect.

It also explains what is happening. My site is still 'offline' to the public so I assume that the Facebook scraper has not had access either to allow it to scrape the new content.

I tested this and seems to be correct. Using Facebook's own Facebook Open Graph Debugger I tried to rescrape with the site offline and found several errors reported and the old content being displayed. I put the site online and rescraped with the debugger and the problems resolved although it did highlight several minor issues I need to resolve.

Good call Melissa and you put me on the right track. When I'm ready with the site I'll have to ensure all the pages are revisited by Facebook to update.

I think this issue can be marked as resolved
